RAIL-JOINT.

Application filed February 18, 1921.

the county of Mercer and State oi. Pennsyh vania, have inventml certain new and use- :liul TIDPIOVGITICHTS in Rail-Joints, o'l which. the following is specification.

This invention relates to rail joints for railway tracks, and it has toran object to provide a novel and improved form of rail joint which will permit of creeping oi the imlividi'ial rails and avoid danger of the same buckling; upon increase of temperature.

ll'lore s 'iccilically speaking the invention has for an object to provide a rail as above set :lorth which maintains the continuity of the tread at the joints and also holds the rail sections or lengths properly against relative displacement either laterally or ver tieally, and also serves to prevent any undesir: ble longitudinal movement of the rail ends away from one another.

For further comprehension of the invention, and 01 the objects and advantages thereof, reterence will be had to the :tollowin description and accompanying drawings, and to the ap iended claims in which the various novel teatures of the invention are more particularly set forth. 7

Figure 1 of the drawings is a perspective view showing a pair of rail ends joined according to the invention.

Fig. 2 is a side elevation of: the separate rail ends.

Fig. 3 is a bottom plan view of the rail ends joined as in 1.

Fig, l is a transverse section taken at the point indicated by the line l--: in Fig.

in the drawings the numerals 10, 11 indicate the rail ends generally. In construct-- inn my improved rail joint the tread. of the rail. 10 has cut vertically therethrough a T-slot 12, the web 10" beinp; cut out under this T-slot as at 13. The base flange 10 of the rail 10 is formed with. a pair of elongated apertures 14 which register with thls cut out part 13.

The rail 11 has the tread 1]. thereof cut out on opposite sides as at 16 flush with the web 11 a short distance from the end of the rail, while the portion. of the tread between this cut out 113 and the extreme end of the rail is diminished in width to form a pair of Specification of Letters Patent.

projections 17, thus iorming a T-head which is adapted to engage in the T-slot 12.

The base flange 11 of the rail 11 is cut away as at 18 from a point in vertical alinement with the inner wall of the cut out 16 in the tread 11 to the end of the rail, the Pl'OjGClllIlg portion 19 of the base flange 10" being accommodated in this cut out. Projertingr downwardly from the web 11 into pair of integral studs 20 which are adapted. to engage in the elongated apertures 14. v

Formed on each side of the web 10 of rail 10 are a pair otangular guide flanges 22 which may extend along the rail from the end thereof to a point slightly beyond the inner wall of the T-slot 1.2. Each 01? these pairs of guide flanges 22 forms, in cooperation with the web of the rail, a T- guide. Each of these T guides is adapted to have engaged therein a bar 24, of which there is one on each side of the rail webs 11, these bars being secured together bya bolt 25 on which is screwed a nut 26, this belt passing through suitable registering apertures in the bars 24: and the web 11.

To provide for relative longitudinal movement of the two rails 10 and 11 the projections 17 are of less dimension, longitudinally ot the rail, than the head of the T-slot 12, while the distancetrom said head of the T-slot 12 to the end of the rail 10 is less than the longitudinal dimension of the cut out 16. The studs 20, being of circular cross section, are permitted longitudinal movement in the apertures 1 1.

In assembling the railjoint the rail end 11 projected over the rail end 10' until the projections 17 register with the head of the T-slot 12 in which position the studs 20 on ail 11 will also register with the apertures 14: in rail 10. Rail 11 is then dropped into position, the projections 17 engaging in the head of the T-slot 12 while the top wall ot the cut out part 18 of the rail 11 rests on the projecting end 19 ot the base flange 10 The bars 2 1 are then slid into the retaining guides formed by the angular flanges and secured in place by the bolt 25.

With the joint as thus constructed it will be noted that there is no break in the continuity of tread of the railroad tracks while at the same time provision is made for limited individual creeping of the rails, while relalows 1. In a rail joint, a air of rail ends one of which has the trea portion presenting a vertically extending T-slot, the other of 7 said' rail ends having the tread thereof cut out on opposite sides flush with the web at a distance from the end thereof, the extreme end of said tread being of diminished width to'form a pair of projections presenting a T-head engaging in said slot, and means looking said rail ends against relative vertical displacement, said means comprising a pair of bars detachably secured to the web of one rail end and retainer guides on the other rail end in which said bars engage slidably.

In a rail joint, a air of rail ends one of which has the trea portion presenting a vertically extending T-slot, and having the web. thereof cut out in vertical alinement with the inner end of said T-slot leaving a projecting base flange portion, the other of said rail ends having the tread thereof cut out on opposite sides flush with the web at a distance from the end thereof. and'having the base flange cut out in correspondence'to the said projecting base flange element. v

In a rail joint, a pair of rail ends one of which has the tread portion presenting a vertically extending T-slot, and having the web thereof cut out in vertical alinement with the inner end of said T-slot leaving a projecting base flange portion, the other of said rail ends having the tread thereof cut out on opposite sides flush with the web at a distance from the end thereof, and having the base flan e cut out in correspondence to the said pro ecting base flange element, and means locking said rail ends against relative vertical displacement, said means comprising a pair of retainer guides formed on the first mentioned rail end, and a pair of bars detachably secured to the other rail. end and engaging in said retainer guides.
